4.2.2 Connection to multiple inverters
When EzLogger Pro is connected to multiple inverters, “hand-in-hand” connection method can be used;
each inverter has two multiplexed RS485 communication ports, and one RS485 port of
the inverter is connected to one RS485 port of the next inverter. Note that port A shall
correspond to Port A, and Port B shall correspond to Port B, and the number of inverters
connected to a single COM port shall not exceed 20.
When EzLogger Pro is connected to the environment monitor , meter and other devices, COM4 port shall be
used.
Schematic diagram of COM4 port is as follows:
